The outspoken Rude Boy singer wasn’t going to let that one slide and fired back at the original tweet: "Grow a dick..... FAST!!!!"

The 47-year-old, who's quite used to being disliked by celebrities, took the opportunity to ask Rihanna if she fancied being a guest on his show - and surprisingly it seems the Bajan popstar may have agreed.

And Piers is already looking forward to grilling the We Found Love singer: “Going to be one hell of an interview now @rihanna - bring your A-game, lady. #CNN.”
